16 Weeks Pregnant Belly
At 16 weeks pregnant, your belly is likely becoming more noticeable as your uterus continues to grow and rise above your pubic bone. For many parents-to-be, this is when the bump starts to look more like a baby belly than just bloating. As your abdominal muscles stretch to accommodate your growing baby, you may feel some round ligament pain, a common sharp or achy sensation in the lower belly or groin area, especially when you move quickly.
Clothing may start to feel snug, so it’s a good time to explore comfortable, supportive maternity wear. Even if you’re not showing much, your body is working hard to support both you and baby, so don’t be surprised if you need more rest than usual. Gentle movement like prenatal yoga, short walks, or stretching can help ease tension and keep you feeling strong.
